Est the given claim. assume that a simple random sample is selected from a normally distributed population. use either the p-value method or the traditional method of testing hypotheses. company a uses a new production method to manufacture aircraft altimeters. a simple random sample of new altimeters resulted in errors listed below. use a 0.05 level of significance to test the claim that the new production method has errors with a standard deviation greater than 32.2 ft, which was the standard deviation for the old production method. if it appears that the standard deviation is greater, does the new production method appear to be better or worse than the old method? should the company take any action? negative 42, 79, negative 25, negative 71, negative 42, 15, 19, 53, negative 9, negative 55, negative 106, negative 106

(round to three decimal places as needed.) (b) find the probability that a randomly selected student received a business degree, given that the student is female. the probability that a randomly selected student received a business degree, given that the student is female, is nothing. (round to three decimal places as needed.)
